Product Introduction

The nearest equivalent grade for NM300 steel would be AR 300 steel. AR 300 is a wear-resistant steel with a hardness of approximately 300 HB. Other equivalent grades may include Hardox 300, Abrazo 300, Roq-tuf AM 300, and Dillimax 300.

Metal sheets made from NM300 steel or its equivalent grades are commonly used in applications that require high wear resistance, such as mining, construction, and agriculture equipment. These sheets are also used in the manufacturing of heavy-duty machinery parts, buckets, liners, and blades.

Metal sheets made from NM300 steel or its equivalent grades have high tensile strength, good toughness, and excellent weldability, making them ideal for use in harsh environments and high-stress applications. They offer exceptional durability and long service life, reducing downtime and maintenance costs.

Product specification
